1 Claim.

My invention relates to building construction, F

and more particularly to construction wherein the walls of a building are formed of concrete slabs or blocks.

The prime object of the invention is to provide a concrete wall construction wherein concrete blocks or slabs are pre-formed in such a manner, that they will rigidly inter-lock with each other, and also with the building superstructure.

Another important object is to provide a concrete block building construction in which the blocks may be laid, or installed, by un-skilled workmen with little or no use of mortar.

At the present time, is is common practice to form building walls by laying thick concrete blocks with mortar and trowel similar to the manner in which stones are laid, and in such construction, the blocks usually constitute the entire wall thickness, and actually form a large portion of the super-structure. That type of construction requires the services of skilled masons, and is therefore expensive. Expansion and contraction through heat variation in that type of wall construction, usually causes excessive cracking at the mortar joints and after a time results in the walls getting out of plumb, which terminates in an expensive repair job.

Construction in accordance with the present invention anticipates the use of comparatively thin concrete blocks which are rigidly anchored to the super-structure, thus cheapening the overall cost of construction, and also eliminating the problem of holding the walls plumb or the future problem of re-aligning them.

The present invention also anticipates the use of widely spaced vertical steel wall studding as a part of the building super-structure, and in-- cludes a means carried ,by the wall blocks for rigidly anchoring them to such studding.

A further object is to provide a type of building construction which may also be used on the inside surface of vertical studding for attaching pre-formed wall paneling thereto.

Another important object of the invention is to provide a type of construction which will produce a building which will be proof against vermin andtermites.

Other objects will be apparent from the accompanying three sheets of drawings, wherein:

Figure 1 is a fragmentary perspective view of a building wall which isconstructed in accordance with the present invention.

Figure 2 is a perspective view of one type of wall block used in carrying out the inventive and '7). .at a forty-five degree angle with relation to the 2 principle, and looking primarily at the inside surface thereof;

Figure 3 is a perspective view showing the outside surface of the block of Fig. 1;

Figures 4 and 5 are views similar to Fig. l, but showing two different arrangements of studding engaging lugs;

Figure 6 is a fragmentary perspective view, partially in section, and detailing a removable studding engaging lug used in connection with the constructive principle; and,

Figure '7 is a fragmentary perspective view looking from the outside at the corner of a building wall constructed in accordance with the invention, and detailing construction at such corner.

Like characters of reference designate like parts in all of the figures wherein they occur.

In the drawings:

The reference numeral I indicates as a whole a solid concrete foundation sill or plate which caps the entire wall foundation of the building. The sill i could well be the upper portion of the wall foundation itself, and in most cases will be so formed.

At laterally spaced intervals, the sill I or the upper surface of the foundation as the case may be, is provided with vertically disposed studding members 2 which are imbedded at their lower ends in the sill i, or which may be otherwise rigidly anchored thereto. The studs 2 are preferably made of steel I-beams, having outside flanges 3 and inside flanges 4 which extend the entire length of the beams. The upper ends of the studs 2 are not shown in the drawings, but they are to be either imbedded in or rigidly connected to a cap plate, similar in extent and construction'to the sill I.

The sills I, studs 2, and the concrete cap plate, not shown, constitute the major portion of the building frame which is completely rigid except for the slight inherent resiliency of the studding. As stated hereinabove, the studs 2 are preferably formed of steel, but good results can well be obtained by making them of reinforced concrete.

At each of the building corners, an especially formed studding member, 5' is provided (Figs. 1 The studding 5 has a vertical Web 6, set

two perpendicular side surfaces of the sill I, and having outside flanges I with outside surfaces lying. parallel to thev outside edge surfaces of the sill I. The web 6 has inside flanges 8 which have inside surfaces lying parallel to the insideedg surfaces of the sill I.

In forming the outside wall of the building: The concrete blocks of Figs. 2, 3, 4, and 6 are used. These blocks may be made of any desired dimension which should be more or less determined by the spacing of the studs 2. It is preferred, however, that they be approximately two inches in thickness.

The edges of the blocks are complementally formed to interlock with each other by a usual tongue and groove arrangement, and are identical in that they each have a plane outside surface. They are all provided on their inside surfaces with lugs for engaging the flanges of the studding, and the lugs are substantially identical except that they are difierently'spaced with relation to the ends of the blocks.

One of the blocks is shown in Fig. 1, and is indicated as a whole by the reference numeral H). The block II] has a smooth outside surface I l and a similar insidesurface I2 which is equipped with two integrally formed oppositely disposed lugs l3 which are adapted to anchor the block to one of the upright studs 2. The lugs 53 are substantially wedge-shaped and their adjacent vertical faces I4 each have an under-cut ornotched portion IS. The notched portions I5 of the two lugs l3 complementally form space for receiving the two outside flanges 3 of oneof the studding members 2. The two oppositely disposed notched portions form lipsl'li which project toward each other over the opposite inside surfaces of the .two flanges 3 to retain the block 10 in engagement with the studding.

The two opposite flanges 3 of the studding members 2 are provided with rectangular edge notches II which permit passage therethrough of the lips l6 so that the blocks may be slid vertically along the studding to its permanent location in the wall. The notches H are provided at suitable spaced intervals in the flanges 3.

A wall block 29 is shown in Fig. 5 which has its smooth inside surface 23 provided with two of the spaced lugs l3. In this instance, the lugs l3 are positioned nearer one end of the block than the other end, and adjacent the other end of the block there is provided a substantially wedgeshaped lug 22 which has an end surface 23 which is bevelled to overlap a flange T of one of the corner studding members 5.

In Fig. 4 is shown a wall block which is designed to be used in cases Where the two ends thereof fall directly upon two adjacent studding members 2, or between a corner stud 5 and an adjacent stud 2. In this block, one of the lugs 13 is positioned adjacent each end of the block as shown. In some instances, one of the lugs I3 will be replaced by a lug 22 as shown in Fig. 1. As a means for assuring a tight fit between the flange engaging surfaces of the lugs l3 and 2.2, wedges 9 will be driven in place, as shown in Fig. 1, and if desired, the wedge may be cemented in place; In completing a wall panel with the wall blocks I0, 20 and 30, there Willbe one horizontal row of the blocks which cannot be installed by passing the lugs l3 through the slots I! in the studding flanges, because in all rows thelugs must lie permanently above or below the notches ll. It is therefore necessary that blocks of the key row have at least one lug which is not pro-formed as an integral part of the block.

In Fig. 6 is shown a block .40 which has a through countersunk perforation 4|, adapted to receive a stud-bolt 42. A separate or removable lug 43, having a threaded bore 44, is provided for engagement with the stud-bolt 42. The lug 43 is preferably made of cast metal, but could well be made of reinforced concrete with a threaded sleeve imbedded therein to receive the stud-bolt.

The invention further contemplates the coveringof the inside surfaces of the studs 2 and 5 with large interior wall panels (Fig. 7) of some suitable fire-proof material such as sheet rock or the like. To this end, the panel blocks 50 are equipped with lugs I3, 22 or 43 as desired.

In installing the outside wall blocks they will be laid as best shown in Figs. 1 and '7 with the vertical joints of each row staggered with relationto the sub-ja'cent row, and the tongued and grooved meeting edges of the blocks will be sealed with some suitable plastic sealing substance such as caulking compound.

It is obvious that the wall blocks of the present invention may 'be laid up more quickly than usual walls of mortar and stone, concrete blocks, or brick, and that the construction under the present invention may be accomplished without the use of skilled masons.

It is also thought to be apparent that a type of building construction has been disclosed hereinabove which will accomplish all of the objects and purposes set forth.

:Some changes in the details of construction over those shown in the drawings and described herein, could well be made without detrimentally affecting the practicability thereof, and I therefore do not wish to be confined to the above disclosed preferred embodiment, further than I am limited by the scope of the appended claim.

I claim: 7

Building wall construction, including: a plurality of pre-formecl concrete blocks; a pair of spaced laterally projecting lugs integral with the inner face of each block; an integral lip carried by each lug, said lip overhanging the lug of which I it is a part, the lips of each pair of lugs project ing toward each other but failing to meet; a plurality of spaced vertical wall studding, each studding including a flat flange against which said block face may rest; and relieved places in the edges of said flange for admitting the flange to the space between the lugs.
